  The only _reasonable_ difference I could forsee is the DOS machine would
have an FPU (usually don't). The IIsi doesn't come with an FPU but you
do get one with either slot-thing-card (NuBus or 030 Direct).
  As far as ALL programs, the sales-slime is probably talking a lot of
BS. The 386sx has a 16 bit data path while the 030 in the IIsi is using
a 32 bit path. This should make an appreciable difference on cpu
intensive programs. Also, I am under the impression that most DOS stuff
is NOT written for a 32 bit instruction set, which would preclude
running on XTs and ATs.
  If this DOS machine is to be running Windows, then I suspect there
isn't a chance in hell of it keeping up.
